3. the lack of standardized means to annotate tree nodes and branches with distinct attributes. Current formats - Nexus or NHX (New Hampshire eXtended) Previous proposals for a XML format for systematic data never gained popularity, possibly due to a lack of supporting software.

4. PhyloXML is an XML language defined by a complete schema in XSD, for describing evolutionary trees, as well as various associated data items various software tools for reading, writing, conversion, and visualization of phyloXML formatted data.

5. The Java command-line "phyloxml_converter" can convert existing into phyloXML. “Decorator" helps the users insert various data types into a phyloXML tree. phyloXML support has been developed for three open source namely BioPerl (module Bio::TreeIO::phyloxml) BioRuby (module Bio::PhyloXML) Biopython (module Bio.Tree.PhyloXML)

6. Data structure is vital for efficient information retrieval,updating and processing As biology dataset are huge less explored, these formats will improve the weak link. So Data structure in XML format is like tree structure so the algorithm for the basic process could be log h.
